When a metal reacts with a salt, it displaces the metal present in the salt only if the metal has higher relative reactivity.
in this case , the displacing metal is same as the metal present in salt. both (being same metal)have same relative reactivity. hence, no displacement . NO reaction.
Answer: 18L
Explanation:
Solving this question would be easier by assigning variables.
so, let x = amount of 67% needed solution
Let y = amount of 42% needed solution.
From the question, we know that
x + y = 42 thus,
y = 42 - x
we also know that the pure herbicide in the 67% solution plus the herbicide I'm the 46% solution must be equal to the amount of pure herbicide in the final solution. Thus mathematically, we have
0.67x + 0.46y = 0.55*42
0.67x + 0.46y = 23.1
Remember, y = 42 - x, substituting this value, we have
0.67x + 0.46(42-x) = 23.1
0.67x + 19.32 - 0.46x = 23.1
0.21x = 23.1 - 19.32
0.21x = 3.78
x = 18
.therefore the amount of 67% solution needed is 18L
75% is the chance that they will have detached earlobes
